SPECIFICATION forming part of Letters Patent No. 627,943, dated June 27, 1899.

Application filed April 27, 1897. $eria1No. 634,171. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. SEELY, a citizen of the United States, residing at Emmetsburg, in the county of Palo Alto and State of Iowa, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sash-fasteners; and it consists in the construction and arrange ment of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to provide a spring-catch which will at once constitute means for supporting a window-sash when raised or lowered in accordance with its use in connection with an upper or lower sash and also form a convenient lock to prevent either sash from being opened.

In the accompanyingdrawings, Figure 1 isa sectional perspective view of a window-frame and sash therein, showing the invention ap- Fig. 2 is a detail perspective view, on an enlarged scale, of the attachment, looking toward the rear and shown applied to a skeleton window-sash in full and dotted lines and the ordinary stop at one side which is adapted to be applied to the parting-bead or other molding for use with the upper sash. Fig. 3 is a detail perspective view of the catch that is secured to the lower part of inside or ogee stop to lock the lower sash closed and looking toward the outer side thereof.

Referring to the drawings,wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates upper and lower windowsash, to which is attached the improved sashfastener, consisting of a plate 2, having a slot therein extending entirely therethrough and provided with a laterally-projecting rounded portion 3 at the lower end communicating with a vertical narrow portion 3 at one side, and in the latter part is movably mounted a vertical finger 4, having a laterally-projecting head 5 at one side which normally extends outwardly through the said rounded portion 3 of the slot, and the entire device is mounted on the side stile of the sash within convenient engaging position. The rear side of said head is concave and has the free end 'of a spring-arm 6 pressing thereagainst to normally throw the said head outact with stops 10, secured at proper intervals on the parting-bead on the upper inner portions of the frame andin recesses in the outer molding or ogee stop of the lower part of the said frame. The stops 10 on the parting-stop of the window-frame extend outward at an angle from their supports, as shown by Fig. 2, and those on the molding or ogee stop are straight plates, all of said stops being in planes inside of the plane of movement of the fastener on the adjacent sash-stile and move over the inner faces of the fingers 4 and engage the shoulders 9 to hold the said upper sash lowered and the lower sash raised. The said tapered lug at the rear of the finger limits the outward movement of the same against the pressure of the spring 6,which alwaysvtends to push the finger 4 and head 5 through the slot in the plate 1 to bring the shoulder 9 normally in engaging position with said stops, and the lowermost and uppermost stops respectively form looks to prevent raising the lower sash or lowering the upper sash from the exterior. The said lowermost stop consists of a grooved plate 11, (see Fig. 3,) having a recess 12 formed in its rear side and at the lower end guarded by an outer lug 13, the base-wall of said recess being inclined, as at 14, to ride over the finger 4 when the lower sash is shut down. The lower end of said lu'g 13 is beveled inwardly and fits in the angle 13 between the upper inner part of the head 5 and the outer edge of the finger 4 where the'latter intersects with said head, and thereby the said lower sash is lock-closed and cannot be raised until the head 5 and finger 4 are pressed inward to clear the lower beveled end of the matically through the medium of the tension of the spring exerted thereon, and said parts are released from the several stops by pressing the said head inwardly, and thereby the sash can be released only on the interior.

From the foregoing structural description the operation will be readily understood, and in raising the lower sash the stop 11 is disengaged from the fastener and each succeeding stop rides over the inner projecting portion of the finger 4, which normally stands inward from the plate 11 and automatically presses said finger outwardly through the slot in the plate until the shoulder 9 passes the same or until the sash has been sufiiciently elevated. The sash will then be allowed to come back and the shoulder 9 rested on the I adjacent stop 10. By slightly raising the said sash and now continuously holding the finger 4 pressed outward by pressure of the hand of the operator applied to head 5 the said sash may be lowered entirely or partially by relieving the finger of manual pressure and allowing the shoulder 9 to engage a lower stop. When the sash is lowered entirely, having cleared the stops 10, the arm t moves through the recess 12 automatically until the lower end of the lug 13 reaches the angle 13, when a secure fastening will ensue, the bevel of the wall of the recess 12 being in such direction as to permit the arm 4 to assume its normal position through the action of the spring 6.

The operation of the fastener on the upper sash relatively to its stops is similar to the one on the lower sash, with the exception that in lowering said upper sash the finger 4 must be pressed outwardly by manual pressure to clear the stops, and, further, that the arm is automatically pressed outward when said upper sash is elevated. The uppermost stop 10 will prevent lowering of the upper sash from the exterior, as the shoulder 9 fits over the top of said stop.

The plate 11 is secured in a recess in the sash and will not present any unsightly 0r disadvantageous projections. It will be understood that as many of the small catches may be used as desired, thereby making it convenient'in holding the window-sash elevated or lowered at any desired elevation or depression.

It will be understood that many minor changes in the construction and arrangement of the several parts might be made and substituted for those shown and described without. in the least departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is- In a sash-fastener, a latch-plate adapted to be secured to the inner face of the sash and flush with the same and provided with a perforation com m u nicating by a laterally-extending slot with a vertical slot, in combination with a pendent angular latch-arm pivoted to said plate to move in said slot and provided on its swinging end with a laterally-extending arm or portion terminating in a springpressed head or thumb-piece for actuating the latch-arm, said thumb-piece moving outward through said perforation in the plate, and projecting stops on the Window-frame for engaging said laterally-extending arm, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE A. SEELY.
